Affirmations - Maybe a Bad Idea?

(Hat tip to Dwayne over a Genuine Curiosity) Fascinating post from Kare Anderson about the flipside of affirmations and whether you should endeavor to think and say good/positive things. The post is called, Repeating Positive Affirmations Backfires For Many of Us. Check it out. Here is a snippet:

I thought of Eric today when I read that Norman Vincent Peale may have been wrong, at least for many people when he advocated saying positive self-affirmations to lift your mood. That oft-repeated notion that feeding ourselves upbeat messages can make us feel better isn’t necessarily true according to Joanne Wood's research.

Wow - provocative. what do you think? I agree with Kare that there ought to be more research into this notion. And I agree with Kare and several commenters who share that transformative power comes with consistent action.
